Two terms you'll likely come across are DVR and NVR. These two systems serve the same purpose, which is storing video footage. But their methodologies differ, and so do their best use cases. Keep reading to learn more about these systems, so you can decide which is best for your needs. NVR vs DVR?

DVR - Digital Video Recorder

A Digital Video Recorder or DVR is often considered the traditional method for storing video footage and has a proven track record in a variety of settings, from retail stores to homes. Each of your security cameras sends all their video footage through a single line to the DVR. The DVR takes this incoming video data and stores it on an internal hard drive. This process is facilitated through coaxial cables, which are connected directly from the camera to the DVR unit. These cables serve a dual purpose, both transmitting video data and providing power to the cameras. Advantages of DVR include its cost-effectiveness and compatibility with older analog systems. Plus, DVRs are relatively low on network bandwidth consumption. On the downside, DVRs usually offer lower-quality video and can be challenging to scale as you can only add a limited number of cameras.

NVR - Network Video Recorder

NVRs are relatively new kids on the block in the world of video surveillance. Unlike DVR security systems, they are built to work over a network, which opens up new possibilities and challenges. In an NVR security system, the heavy lifting is done by the cameras themselves. IP or Internet Protocol cameras process the video data and then send it along to the NVR unit for storage. These cameras connect to the NVR through a standard Ethernet cable, which both powers the camera and transfers data. NVR systems provide higher-resolution footage and are easier to scale, allowing you to add as many cameras as your heart desires. You can even access your footage remotely. However, they are usually more expensive and consume more network bandwidth.

Making an Informed Choice

Your choice between DVR vs NVR is dependent on a variety of factors including your budget, existing infrastructure, and your security needs. Each system has its own set of strengths and weaknesses, and the best choice is one that aligns closely with your specific circumstances.
